The data signals for the accessories are generated on CPU128, and then
transmitted to MS128 CPUKON via MS128 CPU-FC. The following table illustrates
the pin-out of the MS128 CPU-FC Flat Cable.

There is a LED on the front panel of CPU128. During normal operation it blinks
continuously. During a Reset or a Parameter Download it remains on. So, the state
of the system can be monitored by way of this LED.
